LAUNDRY-IRON.

specification of Letters IEatent.

Application filed September 9, 1911.

Patented that. 28, 1913. Serial No. sea-58o.

To all whom it may cancer Be it known that I, DARWIN H. TURNER, a citizen of the United States, residing at Gloucester, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Laundry-irons, of which the following is a specification.

The object of this invention is the construction of certain improvements in details in sad irons or laundry irons which are internally heated by jets of burning gas this application being a revival of my earlier application Serial No. 410,691, filed J an. 13, 1908.

Referring to the drawings forming part of this specification, Figure 1 is a side elevation of a laundry iron made in accordance with my invention. Fig. 2 is a view from beneath, of the top-plate and burner of the iron. F ig. 3 is a horizontal section looking from beneath, on the line X-X in Fig. 4. Fig. 4 is a transverse section on the line YY in F ig. 5. Fig. 5 is a central longitudinal vertical section of the laundry iron.

As shown in Figs. 4 and 5, the main body of the iron consists of the bottom or shoe 1 having sides 2 rising therefrom and preferably integral therewith. Bolted to said bottom and sides is a top plate 3 carrying an operating handle 4. Fixed in said top plate is a supply pipe 5 with which two other pipes 6 and 7 are connected, the pipe 6 being for the combustible gas employed, and the pipe 7 being for supplying air under pressure. Preferably cast as a part of said top plate is a mixing chamber 9 shown in Figs. 3, 4 and 5, and comprising a rectangular chamber divided by a central longitudinal partition 10 into two compartments 11 and 12. Said pipe 5 connects with the midlength of the compartment 11, while from the mid length of the coi'npartment 12 descends a connection 13 to the burner. This burner comprises three longitudinally arranged tubes 14, 14, 15 joined to each other and to said connection 13 by a suitable cross-tube 16; the whole being preferably cast in such form. In the under surfaces of these burner tubes are suitable jet-slits 17 through which the gas is designed to issue in a multiplicity of flames impinging; upon the upper surface of the shoe 1 and thereby heating the latter to a degree proper for the work to be done.

As its name implies, the purpose of the mixing chamber is to thoroughly intermix the two inflowing streams of gas and air in order that the combustion may be both economical and perfect. The products of the combustion escape through the slots 19 at the top edges of the sides 2, while additional air for more perfect oxidization of the fuel, enters through the slots 20 along the bottoms of said sides, as shown in Fig. 4.

The intern'iixing above referred to is caused by the abrupt right-angle turns to which the infiowing gases are subjected; the first being the bottom of the compartment 11 against which the gases first strike and are diverted right and left; then at each end of the partition 10 the gases receive two more abrupt turns, and finally as they descend to the burner, they must again turn at right angles. The result is that the and oxygen are thoroughly intermixed and produce a hot and economical combustion. It is well, of course, to suitably proportion the relative quantities of inflowing gas and air for proper combustion. By having the top plate 3 detachable from the sides and bottom of the iron, and the burner connectedwith the top plate, the burner can be readily removed at any time for cleaning out its jet-slits, or for other purposes.

"What 1 claim as my invention and for which I desire Letters Patent is as follows, to wit;

The combination with a laundry iron, a burner therein, and means for supplying ir and gas, of a mixing chamber consisting of an elongated chamber having a central longitudinally disposed partition. extending part way thereof and terminally spaced from each end of the chamber, said burner being connected with the midlcne'th of one of the two compartments formed by said partition in said chamber, and said supplying means being connected with the midlength of the other of said compartments, whereby the intermixing of the air and gas is thoroughly accomplished.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 3rd day of February, 1911. I

DARWIN H. TURNER.
